Comments: Glass Catfish, also known as Ghost Catfish, are a favorite among children because they are transparent. The bones and even food eaten can be seen. These fish are less shy and very happy when kept in schools, especially when they have real plants in their aquarium to use as a gathering place. Plastic plants dont work as well. Also, the aquarium needs a bit of a current to keep glass catfish content.

Unlike most catfish, this one is not a bottom-feeder. Instead, glass catfish prefer to eat when the food floats through the middle section of the aquarium where they like to swim. Many enthusiasts keep snails or other bottom-feeding catfish with this species in order to keep the aquarium clean.

Glass catfish must be carefully acclimated to the aquarium when brought home. They can be easily stressed, especially during transport from the pet store. Be careful not to add these fish to a community tank with very aggressive fish that might chase or nip them and cause stress.

Its easy to tell when a glass catfish is ill, stressed, or dead: it turns milky white. Keep glass cats healthy by maintaining a clean aquarium. These fish cant tolerate a lot of the medicines commonly used to cure sick fish, so the best medicine is to not let them get sick in the first place. If you can keep them healthy, glass catfish will provide an interesting focal point in your aquarium for up to eight years.

Breeding this fish is very difficult and those available in pet stores are almost always wild-caught.
